Bristlecone pine
Pinus longaeva
Great Basin bristlecone pine is known for its extraordinary longevity and sculptural mountain form. Its story is about persistence in a demanding environment, not fast garden growth.

Bristlecone pine (Pinus longaeva) is associated with great basin mountains. Look for 5 needles per bundle, then confirm with other features and a regional identification guide.
How to recognize bristlecone pine
Short needles grow in bundles of five and remain crowded along branches, making a bottlebrush effect. Developing cones can be deep purple; mature cone scales carry the bristles that give the tree its name.
Where it grows well
A mountain specialist is not automatically an easy backyard tree. Ask a local nursery about climate suitability and the exact botanical name. Rocky Mountain bristlecone pine (Pinus aristata) and Great Basin bristlecone pine are different species.
Before you plant
Appreciate ancient wild specimens without disturbing their roots or collecting material. In a garden, a nursery-grown tree needs a site chosen for drainage and climate, rather than an attempt to recreate the stressed appearance of an ancient tree.
Hardiness and size vary with local conditions and provenance. Use the figures here as a starting point, then confirm with a local nursery or extension service. A hardiness zone alone does not establish suitability.
